Hollow glass bubble fifties and sixties of the 20th century developed a particulate material, thin-walled borosilicate material from sodium made by a special process, closed the tiny sphere, the sphere inside the parcel certain amount of gas, it has low-density, high-low thermal conductivity, low oil absorption, high temperature resistance, dielectric strength, good thermal stability, corrosion resistance, controllable particle size and chemical composition and so on. With the development of science and technology as well as industrial mass production of hollow glass bubble achieve low hollow glass bubble material prices, variety, size increasing, can be widely used in building materials, plastics, rubber, paint, metallurgy, marine and aerospace and other fields. The main expand about this point in insulation performance.
In addition there is a 69-year-old women with colorectal cancer metastasis to the liver, cut off the right side of the large intestine after surgery, six months ago to deal with the remnants of the body radiation therapy of cancer, six weeks later, four malignant tumors was significantly reduced, and necrosis, and later liver left lobe of the new long a malignant tumor, use thermal radiofrequency treatment, and did not present any recurrence of tumor necrosis.
There is a 63-year-old women with ovarian cancer metastasis to the liver and pelvis after failure of chemotherapy, twice injected Y-90 glass bubble, until the volume is reduced and the reduced number of cancer two after surgery surgery to remove the current ongoing chemotherapy observation.
